Decorative panel system

ABSTRACT

A decorative panel formed from at least a display panel secured to a frame. In some embodiments the panel comprises a transparent or translucent display panel and an interchangeable decorative insert disposed between the display panel and a supporting surface. In other embodiments an opaque display panel acts serves the function of both the display and decorative layers. A retaining frame is disposed about the periphery of the panels and retains the layers in generally abutting relation, the retaining frame being removable so as to permit replacement of the decorative insert or display panel. The retaining frame comprises a return flange disposed forwardly of the supporting surface at the position of the groove, such that the display panel is retained by the flange seated in the groove, generally concealing the retaining frame. The panel system of the invention provides a cost effective means of changing the look of cabinetry and other decorative fixtures that is easy to implement and results in little wastage of materials.

FIELD OF INVENTION

This invention relates to decorative panels for cabinetry and the like.

BACKGROUND OF THE INVENTION

Interior cabinetry, for example kitchen cabinetry, utilizes “facings”including doors and drawers to close the cabinetry and conceal thecabinet or drawer interior. Such facing is often decorative, with myriaddifferent styles and textures to choose from. The selected style andtexture creates a ‘look’ intended to have aesthetic appeal.

There are different types of panels used for this purpose. Solid panelscan be made out of materials such as glass, plastic or wood. The maincharacteristic of this design is that the solid material supports themounting and handle hardware as well as concealing the area that thepanel is designed to cover. The panels are permanently finished in oneof a variety of ways. A second type of panel is framed. This type ofpanel is characterized by a frame made of wood, metal or plastic, whichsupports the mounting and handle hardware, while the panel fills in thearea inside the frame. Other types of panels include modern hybridswhere a glass or translucent plastic panel are affixed to a frame oraffixed to a solid panel by glues, fasteners or clasps. In all of thesecases the frame and panel can be finished in different materials, colorsand textures, but with the exception of wood panels, the surface finishof the assembled panel is permanent and unalterable.

Even in the case of wood panels there are limitations on the ability toalter the surface aesthetics. It is unusual in today's age for woodfacings to be hand painted. Typically they are pre-formed with asynthetic surface covering such as Masonite (Trademark), which cannot becovered over in any durable fashion; or factory-finished with a stainand/or varnish that is difficult to paint over, requiring extensivelabour to remove the existing finish, with attendant costs. Moreover,even where the consumer or commercial user could change the facingsusing a paint or varnish, for example where the facings have a woodsurface, it is virtually impossible to reproduce the surface finish withthe same quality as a factory can.

Accordingly, the conventional way of changing the “look” of a kitchen,bathroom, laundry room or other cabinetry-based room is to reface thecabinets. This involves removing the existing facings from cabinet boxesand drawers, and replacing them with new facings. This is relativelyexpensive, and results in a lot of wasted material because the removedfacings (usually custom-fitted to the cabinetry) must typically bediscarded.

It would accordingly be advantageous to provide facings for cabinetrythat can be aesthetically altered at low cost and with little wastedmaterial.

DETAILED DESCRIPTION OF THE INVENTION

While the invention is described below in the environment of cabinetry,it also can be applied to appliance surfaces and other surfacesincluding partitions, dividers and wall panels.

The dimensions of the panel can be made to meet standard or customcabinet specifications, and can be manufactured with the cabinetry orsupplied as a replacement for existing cabinetry in re-facingsituations. Standard mounting and handle hardware can be installed usingconventional methods and tools.

In some embodiments the invention provides a decorative panel comprisinga transparent or translucent display panel and a decorative insert, anda frame surrounding the periphery of the layers to retain the layers ingenerally abutting relation, the frame being capable of being removed ordisassembled in order to permit replacement of the decorative insert. Insome embodiments a supporting layer cooperates with a retaining band tofrom a frame retaining the decorative insert against the display panel.In other embodiments the decorative insert is supported by aself-contained frame comprising frame components. In these embodimentsthe invention provides a facing system for cabinetry that can beaesthetically altered at low cost and with little wasted material,requiring replacement solely of a aesthetic insert, which may berelatively thin and therefore of lower cost than replacing an entiredoor or drawer front. The design of the facing system makes it easy todisassemble and replace a colored or textured insert. The system of theinvention is thus ideal for decorative cabinetry. The panel of theinvention is particularly especially effective as a drawer front panelor cabinet door for kitchen, bathroom or other decorative cabinets. Theinvention also provides a method of forming the decorative panel.

In some embodiments the invention provides a display panel combiningboth display and decorative functions. To change the look of a standardcabinet face, measurements need to be taken for all panel sizes, as wellas hinge and handle locations, then a new panel needs to be manufacturedcomplete with all hinge and handle holes. By changing only a singlelayer serving the function of both the display panel and the decorativeinsert, all that is required is to cut and profile new display panelsand then install on site by disassembling the old panel andinterchanging the display panels. The hinges can be left mounted to theback panel or frame (depending on the embodiment), and the handles needonly be removed from the old display panel and re-mounted to the newdisplay panel. These embodiments accommodate the use of materials thatare naturally opaque rather than transparent or translucent, for exampleopaque plastics, wood, engineered wood, metal and stone, as the displaypanel.

The invention thus provides a decorative panel, comprising a retainingframe, and a display panel transversely supported by a supportingsurface of the retaining frame, the display panel comprising a groove atleast partly surrounding the display panel along perimeter surfaces ofthe display panel, the retaining frame comprising an outer perimeterface forming a side edge of the frame supporting a return flangedisposed substantially parallel with the groove and forwardly of thesupporting surface at the position of the groove, the display panelbeing thereby fixed in position within the assembled frame andreplaceable by disassembling at least a portion of the frame to allowthe display panel to be inserted into the frame or removed from theframe.

The invention further provides a method of forming a panel, comprisingthe steps of: a. providing a display panel comprising a groove at leastpartly surrounding the display panel along a perimeter face of thedisplay panel, b. providing a frame having a supporting surface, theframe supporting a return flange disposed substantially parallel withthe groove and forwardly of the supporting surface at the position ofthe groove, forming a channel, c. inserting the display panel into thechannel, and d. affixing the frame around the display panel to retainsaid display panel, the retaining frame being removable so as to permitreplacement of the display panel.

FIGS. 1 to 5 illustrate a first embodiment of a decorative panel 10according to the invention. The panel 10 comprises a front surface 12, atop edge 14, side edges 16, 18 and a bottom edge 20 defined by aretaining frame 40, and a rear surface 22 opposite the front surface 12.The panel 10 is suitable for mounting to cabinetry, appliances or anyother structure in which a decorative surface is desired.

FIG. 2 illustrates the layers of the panel 10 of FIG. 1 in explodedview. The panel 10 comprises a transparent or translucent layer such asa display panel 30, and an interchangeable layer such as decorativeinsert 32. In this embodiment the panel further comprises a supportinglayer such as back panel 34 which together with a retaining band 39 forma retaining frame 40, for holding the display panel 30 andinterchangeable decorative insert 32 together in surface-abuttingrelation as an integral unit (as shown in FIG. 3).

In the preferred embodiment the display panel 30 is transparent ortranslucent, being formed from glass or plastic, allowing light to passthrough so that the interchangeable insert 32 is visible behind thedisplay panel 30. The back panel 34 is preferably rigid and strongenough to support the mounting and handle hardware, composed for examplefrom medium density fibreboard (MDF) or another low cost material. Theback panel can alternatively be made of a frame and panel combination.This would be used for either large panels where weight is a concern orfor doors/drawers where a more elegant aesthetic is desired. Theinterchangeable insert 32, which provides the decorative finish in theassembled panel 10, is held in abutting relation between the frontdisplay panel 30 and the back panel 34.

In this embodiment these components are held together by a removableretaining band 39 forming a shallow channel 45 having a floor 40 a andsides 40 b, 40 c, which together with back panel 34 forms a retainingframe 40. The retaining band 39 may be formed (for example stamped orextruded) from aluminum, sheet steel, plastic or any other suitablematerial. The retaining band 39 and the back panel 34 thus operatetogether to form a supporting frame 40 for supporting theinterchangeable insert 32 in abutting relation with the front displaypanel 30.

The retaining band 39 is preferably formed as one piece, and can beopened and closed to allow for easy assembly and disassembly of thepanel 10. The ends of the retaining band 39 are butted up against oneanother and the retaining band 39 may thus be held in the closedposition with a fastener affixing each end of the retaining band 39 tothe back panel 34, as shown in FIG. 4. In the case of larger panels, theretaining band 39 may be made of two or more portions (not shown), witha fastener at each end affixing the portion of the retaining band 39 tothe back panel 34 in abutting relation such that the retaining frame 40can be disassembled when it is desired to change the replaceabledecorative insert 32. The fasteners 42 are preferably positioned alongthe retaining frame 40 so as to be hidden from sight from a normalviewing position. For example, the fasteners may be wood screws that arecountersunk and located along an edge of the panel that is difficult tosee, such as the top edge of an upper cupboard door or the bottom edgeof a drawer face.

One side 40 a of the channel 45 engages into a groove 30 a surrounding(or partly surrounding) the perimeter edge faces 30 b of the displaypanel 30, i.e. the faces about the periphery of and orthogonal to thelarge faces of the panel 30. In the preferred embodiment the portion ofthe display panel 30 which sits in the channel 45 is recessed, as shownat 46 in FIG. 3, so that the retaining band 39 (and thus the retainingframe 40) is flush with or slightly inset from the bottom edge of thedisplay panel 30. The retaining frame 40 is thus largely concealed fromview when observed from the front of the panel 10. The other side 40 cof the channel 45 rests in a notch 34 b surrounding (or partlysurrounding) the back panel 34 near the perimeter of the back panel 34,preferably (but not necessarily) along its rear surface. With the notch34 b disposed along the rear face 34 d of the back panel 34, the portionof the back panel 34 between the notch 34 b and the perimeter edge face34 c is also preferably recessed from the rear face 34 d of the backpanel 34 such that the exterior face of the retaining frame 40 is flushwith the rear face of the back panel 34. Thus, in the embodimentillustrated the back panel 34 and interchangeable insert 32 are slightlysmaller in dimension than the front surface of the display panel 30.This generally conceals the side 40 b of the channel 45, for aestheticpurposes, but also avoids the collection of dirt and grime, or theseepage of liquids that may spill or spray onto the front surface ofpanel 10 into the channel 45 of the retaining frame 40, which isparticularly advantageous in a kitchen or bathroom.

The visible exterior surfaces of the retaining band 39 are preferablydecorative also, since at least some of these surfaces are visible whenthe panel 10 (for example a cabinet door or drawer face) is in the openposition. The interchangeable insert 32 preferably (but not necessarily)fills the entire available area within the retaining band 39, to thusoverlay the entirety of the back panel 34.

The length of the side 40 c of the retaining band 39, which extendsabout the rear face of the back panel 34, is formed as necessary so asto not interfere with door hinge hardware, but is large enough tosecurely grip the back panel 34 and may have a slight acute angle sothat the flexible retaining band 39 can compensate for differentthicknesses of insert or manufacturing tolerances. The side 40 b theretaining band 39 is preferably made as small as possible so as not tointerfere with direct visibility of the interchangeable insert 32, whilebeing large enough to hold the display panel 30 securely in position.The sides 40 b, 40 c of the retaining band 39 may be mitered or roundedat the corners so as to allow the retaining band 39 to close around thepanel 10.

To form the panel 10, an interchangeable insert 32 of the appropriatesize is positioned between a display panel 30 and a back panel 34. Theretaining band 39 is placed around the periphery of the composite panelarrangement, such that the side 40 b sits in the groove 30 a and theside 40 c sits in the notch 34 a. In the preferred embodiment a bead 40d formed along the rear side of the retaining band 39 seats in acomplementary groove 34 b formed at the end of the notch 34 a, eithercontinuously or intermittently around the periphery of the panel 10. Inthe embodiment shown, when the retaining band 39 is disposed over theedge of the panel 10 the bead 40 d is lodged in the groove 34 b so as toprevent the retaining band 39 from dislodging along the direction of theplane containing the panel 10, which is optional but provides a moresecure attachment to the assembled panel 10.

The retaining frame 40 is fastened to the panel 10, and simultaneouslyinto the closed position, by fasteners 42 disposed through theprojecting tongues 43 and into the side edge faces of the back panel 34.The panel 10 assembled in this manner can be mounted to a drawer,cabinet box or other structure in conventional fashion, the hinges beingaffixed to the back panel 34.

To change the decor of the panel, the fasteners 42 are removed to openthe retaining band 39, removing the side 40 b from the groove 30 aaround the perimeter of the display panel 30 and the side 40 c from thenotch 34 a about the back panel 34, and thus releasing the display panel30 from the back panel 34. The panel 10 can then be reassembled, asdescribed above, with a different decorative insert 32 disposed betweenthe display panel 30 and the back panel 34.

For a different effect to the decor, and to entirely hide side 40 b fromthe front view of the panel, it is possible in this embodiment tocombine the display panel 30 and decorative insert 32 into a singledecorative opaque panel (not shown). For example, this avoids the needto take measurements for panel sizes, hinge and handle locations. Bychanging only a single layer serving the function of both the displaypanel and the decorative insert, all that is required is to cut andprofile new display panels and then install on site by disassembling theold panel and interchanging the display panels. This saves considerabletime in installation and manufacturing.

FIG. 5 illustrates a further embodiment of the retaining band 39 havingribs 40 e which aid in straight forming the retaining band 39 through anextrusion die. In this embodiment the back panel 34 comprises an overlay48, for example formed from transparent, translucent or opaque acrylicsheet. The overlay may be laminated to the wood portion of the backpanel 34 as illustrated, or may be held in position against the woodportion of the back panel 34 by the retaining band 39, which would allowa further decorative insert panel (not shown) to be mounted between thewood portion of the back panel 34 and the acrylic overlay 48, forexample to impart a decorative finish to the back of a cupboard door. Inthis embodiment the notch 34 a and groove 34 b are formed in the acrylicportion 48 of the back panel 34.

In a further embodiment of the invention illustrated in FIGS. 6 to 10, adecorative panel 50 is formed from a display panel 30 and aninterchangeable decorative insert 32. The display panel 30 anddecorative insert 32 may be as described in the previous embodiment. Inthe embodiment of FIGS. 6 to 10 the supporting frame holding theinterchangeable insert 32 in abutting relation between the front displaypanel 30 the display panel 30 comprises a retaining frame 60, which alsoholds the decorative insert 32 against the display panel 30, so that aback panel (34 in the embodiment of FIGS. 1 to 5) is not required. In acupboard door utilizing this embodiment, the hinges (not shown) aremounted between the cabinet box (not shown) and the frame 60.

The retaining frame 60 in this embodiment may be composed of framecomponents 62 each having the length necessary to create a panel 50 ofthe required size. In the embodiment shown each frame component 62 isformed from an extrusion, for example of metal (such as aluminum),plastic or another suitable material. The frame components 62 may beaffixed together in any suitable fashion, for example by corner keybrackets 52 as shown, so that at least one component 62 can be removedfrom the frame for access to the interchangeable insert 32. In theembodiment shown set screws 54 disposed through complementary threadedopenings in the rear face 65 of the frame 50 are tightened to bearagainst the corner brackets 52 to maintain the frame 60 in an assembledcondition. The set screws 54 at each end of a frame component 62 areloosened to release the respective corner brackets 52 and allow theframe component 62 to be removed from the assembled frame 60, as shownin FIG. 10.

Each frame component 62 comprises a front bearing wall 64 having areturn flange 66 along (or partially along) its outer perimeter face 62a, best seen in FIG. 8. The return flange 66 is spaced from the bearingwall 64 to form a channel 68. The return flange 66 engages into thegroove 30 a surrounding (or partly surrounding) the perimeter edge faces30 b of the display panel 30. As in the previous embodiment, the portionof the display panel 30 that sits in the channel 68 may be recessed sothat the frame 60 is flush with the bottom edge of the display panel 30as shown(or slightly inset from the bottom edge of the display panel 30,not shown). The frame 60 is thereby largely concealed from view whenobserved from the front of the panel 10. As in the embodiment of

FIGS. 1 to 5, in the embodiment illustrated in FIGS. 6 to 10 theinterchangeable insert 32 is slightly smaller in dimension than thefront surface of the display panel 30 and the perimeter edge of theinterchangeable insert 32 thus sits in the channel 68 with the recessedportion of the display panel 30.

The bearing wall 64 may comprise a gasket 56, for example adjacent tointernal face 57 of the frame component 62, against which the displaypanel 30 presses the interchangeable insert 32, which both preventsrattling of the display panel 30 against the bearing wall 64 and helpsto fix the insert 32 in position.

To form the panel 50, the display layer 30 is placed face down onsurface. The decorative insert 32 is placed on top of the display layer30 (if not already adhered to the display layer 30). The framecomponents 62 are positioned around the display layer 30, such that thedisplay panel 30 forms the front face of the panel 50 as shown in FIG.10, inserting corner brackets 52 loosely into the frame components 62.The frame components 62 are moved toward each other so that flanges 66fit into grooves 30 a. When the return flange 66 of the remaining framecomponent 62′ seats in the exposed groove 30 a, the mitered corners ofthe remaining frame component 62′ abut the mitered corners of theassembled frame components 62. The set screws 54 are then installed andtightened to secure the frame 60.

In the case of a door embodying the panel 50 of FIGS. 6 to 10, thehinges (not shown) may be conventional cabinet hinges and may be mountedto the rear surface of the frame 60 and the cabinet boxes inconventional fashion. The handle (not shown) can be removed from thepanel 50 and re-attached to the panel 50 after the new decorative insert32 has been mounted, or a new handle can be mounted through the newdisplay panel 50.

A further embodiment of the invention, illustrated in FIG. 11,provides apanel 70 comprising a single layer forming a display panel 72, combiningboth display and decorative functions, along with the frame 60 of theembodiment of FIGS. 6 to 10. The embodiment of FIG. 11 may be employedwith rigid opaque materials such as (without limitation) plastic, wood,metal or stone as the display panel 72. The groove 66 (and optionallythe recessed portion of the perimeter edge surface) can be routed ormilled into the perimeter surfaces of the display panel 72.

Thus, to replace the display panel 72 in a door with a display panel 72of a different decor, the door is removed from the cabinet box (in manycases the hinges can be split by a quick-release) and the frame 60 isdisassembled as previously described. The display panel 72 is removed byreversing the assembly procedure described above and the new displaypanel 72 is mounted by reassembling the frame 60 as described above.

In the case of a door embodying the panel 70 of FIG. 11, the hinges (notshown) may be conventional cabinet hinges and may be mounted to the rearsurface of the frame 60 and the cabinet boxes in conventional fashion.The handle (not shown) can be removed from the panel 70 and re-attachedto the panel 70 after the new display panel 72 has been mounted, or anew handle can be mounted through the new display panel 72.

FIG. 12 illustrates a further embodiment in which the display panel 72also forms the decorative insert. In this embodiment the framecomponents 62 are provided with an inner ridge 80 for retaining a rigidback panel 34 against the display panel 72, to resist flexing and‘billowing’ of the centre portion of the display panel 72. In thisembodiment the composition of the back panel 34 may be as described inthe embodiment of FIGS. 1 to 5 and is dimensioned to fit within theinternal face 57 of the frame 60 and the ridge 80. The ridge 80 at leastpartly surrounds the inner portion of the frame 60, to retain the backpanel 34 in snug abutting relation to the display panel 72. If the framecomponents 62 are formed as extruded components the ridge 80 wouldcircumscribe the internal faces 57 of the frame components 62.

FIG. 13 illustrates a further embodiment of the panel 70 having atransparent or translucent display panel 30, as in the embodiment isFIGS. 1 to 5, and a decorative insert 32 is disposed between the displaypanel 30 and the back panel 34, visible through the display panel 30from the front of the panel 70. The back panel 34 resists flexing andbillowing of the centre portion of the decorative insert 32 and holdsthe decorative insert 32 in position.

If the decorative insert 32 is particularly thin and unable to beself-supporting, for example a film, it may be removably laminated orotherwise adhered to the display panel 30 before the display panel 30 isinserted into the frame 40 or 60 to ensure that the decorative insert 32remains in position without sagging or creasing. In this case thedecorative insert 32 is replaced by removing the display panel 30 asdescribed above and peeling the decorative insert off of the displaypanel 30. If the new decorative insert 32 is similarly too thin to beself-supporting, it can be adhered to the display panel 30 in likefashion before the display panel is reinserted 30 into the frame 60. Ifa thicker decorative insert 32 is used to replace the previousdecorative insert 32, a thinner display panel 30 can be used toaccommodate the greater thickness of the decorative insert 32 within thechannel 45 or 68.

Modifications of the invention may be made without departing from thescope of the invention described herein. For example, withoutlimitation, the decorative insert may be adhered to the back panel orthe display panel; other layers, partial layers and hybrid layers may beadded or substituted for the layers illustrated (for example adecorative insert may be applied to or fixed within the frame overlayingthe rear surface of the back panel); or the display panel may beprovided with a colour and/or texture to complement or add designelements to the decorative insert layer. The invention includes all suchmodifications and adaptations as fall within the scope of theaccompanying claims.
